You could try Pygmy cories, cardinal or neon tetras and 1 dwarf gourami with pwc's every 3 days or..6 corydoras habrosus for the bottom, a small schooler like ember tetras(6-8), chili rasbora(8-12), or microdevario kubotai(7-10), and for centerpiece fish 2 or 3 sparkling gourami or scarlet badis. Just a ton of suggestions !
